i have these two cacti i bought from a store. they were looking unloved. they look a little better now with a little TLC even from a newbie like me. i think they are echinocactus grusonii and opuntia monacantha? but i want to be sure so i dont kill them

Bottom one is Opuntia Monocantha Jacob's Coat, or a variation of it.
First one, duno.

thank you for the replies.
glad to hear i was close enough with the opuntia monocantha. i think it might be a monstrose of opuntia monocantha, which is why it looks fucked up 
i will treat the first one as a echinocactus grusonii for now until i can positively ID it. i will pay close attention for signs of stress.
thank you for the help guys.

Def not echinocactus grusonii, they have very defined ribs and I think the spines are very different as well.
Mammillaria? Maybe marksiana? I haven't been staring at cacti for hours a day in many years...

thanks for the reply. i asked elsewhere about these IDs too and i was told that the echinocactus grusonii was correct. i thought the same as you, so i asked why there were no ribs and instead it was an alternating pattern and they said it was because it was young. i have no reason to believe this person over anybody else so i was not 100% convinced (ther are so many similar looking cacti!). your suggestion of Mammillaria grusonii looks much closer to me. the marksiana does not look quite right i dont think judging by pictures on duckduckgo.
that said, while looking at images of (claimed to be) echinocactus grusonii i found this page: http://web.tiscali.it/rosgiana/schede/echinocactus_grusonii_v._albispina.htm which does look perfect, but when searching for images of the v. albispina version most of them have ribs, so i suspect this is a misidentity too (i am new to cacti, but i already get the impression misidentifications happen a lot). your suggestion is the closest i have seen so far. i will research their needs and hopefully they are close enough that it wont matter and i can see how it developes and maybe make a more positive ID later.
for now i am going to primarily assume it is Mammillaria grusonii because your suggestion looks much closer.
thank you very much for your help, particularly for spending the time to go through possibilities for hours! i tried that but was overwhelmed by how many cacti looked the same, even after hours of trying to seperate features!
thank you so much for the help! <3
edit: i just had another look at images of Echinocactus grusonii v. albispina and it actually looks like about 40% of them do look similar to mine. hmmmmm
