If you give the succulent (second picture) gradually and carefully more sun and a bit of time, it'll get more distinctive features that can help with getting a more confident ID.

First looks like a Notocactus / Parodia with a fake flower.

I think the first one is some kind of mammillaria. Not sure what kind. There are a lot. Maybe someone else can be more specific.

The glued on straw flower can be tricky to remove. You’ll likely loose a few spines in the process.

The cactus my guess would be some sort of Echinocereus. Besides the fake flower I think you’ve got a seed pod from last year’s flowers or a flower bud. I can’t really tell, but if you do get a flower post a pic so we can figure out the species.

So i removed the flower a while ago and let it grow but it still hasnt grown any arms and to tip is starting to turn brown a bit

This isn’t the type of cactus that grows “arms”. Do an internet search for “Echinocereus” so you can see the typical characteristics of your plant.

See where it’s fatter at the bottom and getting skinnier as it goes up? That’s a sign that it’s not getting enough light. It needs much more light than it’s been getting.

Also, I just looked at your picture again and noticed that the soil looks like it needs more inorganic material. A lot of people here mix in half perlite or pumice to the c&s mix to promote better drainage. Heavier growing medium retains water and promotes root rot. Maybe that could be what caused the brown tip you mentioned...? Can you take a picture of that so we can see it a little better? I can’t really see it from the angle of the image above.

I said something about arms since it used to have them when i first got it, but it has since lost them.(dying, my cat, and accident while removing the
