    Welcome to fishlore!
    Well, first of all you have some stocking issues, mollies get pretty big, and have very large bioloads with 30g being their min tank size, also cories need a min of 15g although bigger is better though.
    so I'd advise you to rehome them or upgrade to a bigger tank, but the good news is your guppies and glowlight tetras can stay.

    Im saving up for a much bigger set up. this was my first tank. But until then do you think removing some of the decor would help them destress?

    BTW thank you for your help!

    No problem!
    no need to remove any decor, as long as there is some open space, it will help the other fish escape out of sight of the molly, and even if you get a new tank it will take a while to cycle it, so... might not be such a good idea, I'd return/ rehome them, then after you cycle your future tank, we can help you stock again.
    Btw what size tank are you planning on?

    Welcome to the forum :)

    Depending on the sex of your molly and guppy, he/she could be trying to mate since the two species can cross breed. Either that or the molly is being aggressive because of the limited space.

    Sorry to say but none of the fish you have except the guppy are appropriate for a 10g. The corys and tetras need to be in a group of 6+ but that would overstock your tank even more. Glad to hear you're upgrading though.

    And sorry to hear about the guppy. Is the tank cycled?

    Welcome to fishlore...

    Since your tank is overstocked... You can try to do is keep your mollie in a bucket for few hours and then again reintroduce it to the tank. Hope it helps.
