Yes, you could screen print these designs but it's not just as easy as what mesh count to use. You will need to build yourself up to the more complicated artwork. You have what looks like to be 2 spot color designs and 1 CMYK or simulated process piece of art. How you want to print these and on what color shirts can affect how you will want to set the job up.

This article is about mesh count:http://www.catspitproductionsllc.com/sc ... sions.html
Here's a general guide and a video:
Use a 28 to 30 mesh count for printing many brands glitter inks. Always check with the manufacturer of the ink about this. This mesh will print a very high volume of ink and have a thick coat of emulsion making it difficult to expose.
Use an 85 mesh count for athletic printing, opaque ink deposits, thick puff ink, and some shimmer inks. This mesh will print a very high volume of ink and have a thick coat of emulsion making it difficult to expose.
Use a 110 mesh count for heavy coverage on dark shirts, solid under base prints, puff, metallic, some shimmer inks, and for certain transfer printing. This is a great mesh count for high opacity inks on any dark garments.
Use a 155 or 160 mesh count for general printing on white tee shirts & under basing on dark shirts, prints on nylon jackets, and thinner silver shimmer inks. Many thinner plastisol inks will print well with this mesh count.
Use a 195 mesh count for printing on light colored T-shirts with fine detail, line work or halftones of around 35 LPI.
Use a 230 mesh count for printing on light colored tee shirts with fine detail, line work or halftones of around 45 LPI.
Use a 305 to 355 mesh count for process color on light shirts, or for overprinting a halftone on a white under base on dark shirts. You should be able to pull of halftones of up to 65 LPI but a 55 LPI is most common.
Most lower mesh counts will always be colored white. Dyed or yellow mesh starts at about 200 mesh and higher. If you have been using a 156 or 160 mesh count or lower that is yellow or amber in color, that is a specially dyed mesh and is not normal to find.https://www.youtube.com/watch?v=kq9FXZ0Tmmg
