Indeed, there is a ‘jungle’ of (misleading) metrics around (see for a pretty comprehensive list: https://beallslist.net/misleading-metrics/ ). The ‘impact factors’ you mentioned are examples of such misleading metrics:
SJIF (Scientific Journal Impact Factor)
RJIF (Research Journal Impact Factor)
The SCImago Journal Rank (SJR): https://www.scimagojr.com/journalrank.php is based on Scopus data and is a service that ranks journals. Scopus have their own ‘impact factor’ called CiteScore.
Being really precise there is only one impact factor. That is the impact factor assigned by Clarivate (https://mjl.clarivate.com/home ) which is given to journals indexed in their SCIE (and SSCI) database.
