Mammillaria gracilis and Mammillaria elongata across the top. Bottom one looks like it may be a Mammillaria sp as well.

Re: Cacti Identification Assistance
I agree. Bottom one looks like M. magnimamma.

Re: Cacti Identification Assistance
The top two are definitely right but I would say mammillaria mystax on the bottom one.
Re: Cacti Identification Assistance
The two back plants have been grown in very poor light, probably in the store, and have etiolated. They obviously need to be in better light, but don't put them in full sun too quickly as they may be tender and burn. Cacti are really not house plants in the sense they can be grown anywhere in the room but needing to be near to a window for maximum light intensity. However watch they do not burn behind glass. You can even put them outside in summer when all danger of frost is past.

Re: Cacti Identification Assistance
Thank you all very much. This info is very helpful. DaveW, I am curious how you can tell the two in the back have been grown in poor light. While you are correct, I did buy these at Home Depot, the one on the left has grown almost an inch since I bought it a month ago. The one on the right has grown quite a bit, too, but not as much. I don't doubt they need more light, but they seem to be doing very well. (But, again, I'm new to growing cacti.)
Re: Cacti Identification Assistance
Don't worry we all have to learn to cultivate cacti. It's what is known as etiolation. The plant becomes longer and lighter green with a greater distance between the areoles and spines than is normal due to lack of light intensity. Unlike many house plants most cacti are high light intensity plants used to much sunnier conditions than the interior of a room will provide. They usually have to be grown on the windowsill for maximum light.
A lot of people new to cacti think if they get rapid green growth similar to other plants that are doing well, but cacti are really slower growing than your average house plant and will produce lank light green growth if grown in poor light and be poorer flowering. For instance here is a picture of your back right hand plant Mammillaria elongata grown well in good light:-

Re: Cacti Identification Assistance
Back right is an etiolated Mammillaria microhelia, back left looks like Mammillaria gracilis, front is either Mammillaria mystax or Mammillaria nejapensis

Re: Cacti Identification Assistance
Mammillaria microhelia is usually single stemmed and will have some centrals toward the apex. This is a regular M. Elongata. If you are referring to maybe the hybrid pink nymph, that also has centrals
