Those are quite doable, just as @MrBeaver noted, the corners are tight and will cut at the radius of the endmill you use.
Flat stock w/ large open areas can be a pain — if you don’t remove everything as a pocket (which takes forever) you wind up in a slotting situation which can be difficult for the machine to cut. Doing the design w/ insets of greater than 10% of the largest endmill diameter which you are using helps (so that they can be cut as pockets rather than slots), as does roughing w/ a larger endmill, then making a finishing pass w/ a small one. Another strategy is to cut w/ a V-bit first, which will establish details, then cut through the profiles w/ a small endmill.
Another consideration is your experience level w/ vector/Bézier curve drawing — you’ll need to understand Boolean operations to make the above design, and you’ll want to make two versions of each project, one w/ the text as text, and another which has the text merged into the design so as to finish up CAM for that central part.
You should be able to at least start on doing these entirely in Carbide Create if you don’t have experience w/ some other vector tool — if/when you run into its limitations you can use pretty much any other vector editor (I use Macromedia Freehand) — typical options are:
