Would complex life evolve on this planet, and could humans survive on it without much outside help?

Okay, as an extension of my previous question, I'm just going to lay bare all the details I've written down about this planet (including corrections from my last question), and ask the big question that needs to be answered about this planet. Can it support life, and if so could humans colonize it without resorting to wearing space suits or building bubble habs?

Anthemusa

Physical characteristics:

• Earth-like exoplanet located 600 light years from Sol in the sextenary star system Messina 2247
• Mass is $1.696*10^{24} \text { kg}$ or $.284$ Earths, resulting in a surface gravity of approximately $.66 \text { g}$, or $6.44 \text { m/s}^2$
• Planetary diameter of $8380 \text { km}$, with an orbital radius of $1 \text { AU}$ around its mother star, Scylla β

Side Note: Scylla β is the second ordered star in the Messina system that orbits the black hole Charybdis as part of an ordered sextenary (six star) hierarchy; the hierarchy is made up of six stars designated Scylla α - ζ (each $.1 \text { ly}$ distant to each other), while Charybdis is the primary mass around which they all orbit, with an approximate mass of $315 \text { Suns}$

• Atmosphere is $35\% \text { oxygen}$, $61\% \text { argon}$, $1.07\% \text { carbon dioxide}$, and $.93\% \text { arsenic}$ particulates, as well as other trace elements which make up the remaining $2\%$
• Due to a bombardment of high-energy particles from the star Charybdis going hypernova during the early stages of the planet's formation, the planetary crust of Anthemusa is laced with negative mass exotic matter which can be extracted to fuel warp drives as well as other negative energy/antigravity technologies

Environmental hazards:

• Atmosphere is easily breathable after acclimatization but has had some unfortunate side-effects on the planet, like gigantism in local fauna similar to the prehistoric epochs of Earth (also due in part to microgravity and the bizarre effects of exposure to exotic matter during the early stages of evolution) and a drastically increased risk of out of control forest fires, as well as arsenic smog

• Atmospheric composition also causes metal to rust faster, and food to spoil more quickly. However, after acclimatization, the higher oxygen levels result in increased stamina and endurance. It also increases the rate at which cells decay however, resulting in a moderate reduction in overall life expectancy and an increased risk of cancer (gene therapy has mitigated these effects somewhat)

• Because of the thin diffusion of arsenic smog over the planet, the poisonous particulates mix frequently with large bodies of water, making all non-filtered water poisonous unless it's extracted from deep underground. The smog can also increase in density from time to time, resulting in roving clouds of toxic poison that will occasionally pass through the forests, killing anything that breathes it.

• Exceptionally large deposits of exotic matter can occasionally lead to the formation of large floating landmasses that are lighter than air due to their negative mass.
• Anthemusa's sextenary star system makes a true night rare, and often the only reprieve from the sunlight on the planet are brief periods where it becomes slightly dimmer as the number of suns overhead decreases; most animals on Anthemusa are cold-blooded as a result, as warmth from the suns is always plentiful.

Please let me know what you think, and if there's anything about this planet as I've described it that doesn't make much sense from a scientific standpoint.

EDIT: Also I've just started using this site, so please bear with me while I figure out the formatting :)
