This can be done on a variety of tool (locally or online).
https://www.gear-genomics.com/teal/ this is online
https://labsquare.github.io/CutePeaks/ this you can download and has a bit more features
Remember to check both forward and reverse and trim at need.
16S are long and shady. Just a forward read doens't quite get you there with confidence. So we sequence both wasy to have better quality coverage.
We can use https://www.ebi.ac.uk/jdispatcher/sfc
Look for emboss_seqret
Same website. There is diffrent one you can use (MSA are also fine generally speaking).
https://www.ebi.ac.uk/jdispatcher/psa
We want to generate a consensus sequence to get a better taxonomic inference
https://www.ebi.ac.uk/jdispatcher/msa/emboss_cons
We can use good old blast for that
https://blast.ncbi.nlm.nih.gov/Blast.cgi?PROGRAM=blastn&PAGE_TYPE=BlastSearch&LINK_LOC=blasthome
or directly on SILVA
This is also a cool website to look at environmental distribution of the subject
Once you have taxonomic info, you can also search on BacDive for more phenotypical infos

You can either download the alignment directly from NCBI, or select a few sequences and make a new one. Then make a tree out of it and download it for viz

Finally, you can head iTOL to view and edit your tree
