There are a lot of problems with your plan. Don’t feel bad though–as a beginner, you’re not supposed to know how to learn/practice efficiently instead of wasting your time doing things the wrong way. If everybody knew how to do it, I wouldn’t be teaching a workshop on it.
Don’t set goals based on how many of xxx you’ll do a day. That’s useless to you because as a beginner, you’ll be very slow and you’ll mess up often, and you won’t be able to do nearly as many things in a day as you think you could. Just one still life might take you a few days to do at an acceptable level, let alone doing 8 in one day plus all the other stuff you listed.
Instead, you base your goals on the amount of time you’ll dedicate to your study. So instead of saying you’ll do 8 still life drawings in a day, you would say you’ll do x number of hours still life drawing in a day. It doesn’t matter how many drawings you do–quality over quantity.
Don’t bother trying to do any kind of figure/anatomy/gestures from imagination. That is not for beginners. In fact, don’t do anything from imagination or even replicating from memory. That is useless for beginners. You have much more important tasks to tackle as a beginner.
Also, don’t bother with any kind of timed drawing. Speed is not your concern, and it should never be your concern as an artist. The only time it matters is in commercial art where you have tight deadlines, but you worry about that when you have gotten good enough to do professional quality work and need to compete in the marketplace. You are far from that right now, so don’t even think about speed.
(See, this is why I teach a workshop on this. There is so much misinformation, misguided mentalities, and confusion, due to the overwhelming amount of bad information on the web.)
What you need to focus on, are the critical foundations like anatomy/figure studies, perspective, composition, values, colors, etc. You need to first gain the basic technical skill of reproducing what you see convincingly. If you can’t even take a picture and reproduce it faithfully and accurately (as if your version is a replica that looks like the original), then that’s the first thing you need to master, because everything else you learn later will depend on this basic ability of eye-to-hand coordination and observation/analysis.
