Will these dents make this aluminum bike frame unsafe
Noone can answer this authoratively for you.

The common suggestion is for you to include this area of the frame in your monthly maintenance.  Look at it super-close and look for changes over time.

One aid is to take a photo of the area from a cellphone or similar, every month, and look for variation.  Try and keep the lighting and angles the same, and roughly the same time of day.

If the area doesn't change over time, you're probably good.  If it does move and change, stop riding and re-evaluate.
