Should I use SLF4J or log4j?

Using SLF4J means that replacing the implementation is very easy if company policy changes, e.g. when your company is acquired and new policies forced on you. Using SLF4J now, when you write the code, will take no more time than using Log4j directly. Replacing direct Log4j calls later will take a lot of time.

Can we use log4j and SLF4J together?

Once you have places both jar files in your application classpath, SLF4j will automatically detect it and start using log4j for processing the log statements based on configuration you provided in log4j configuration file. So essentially, SLF4J does not replace log4j, they work together.

The main difference is that SLF4J is using static binding while commons. logging is using some resolution strategy. Logback (the “native” (i.e. there is no additional wrapper layer) implementation of the facade) is comparable to LOG4J but has a richer API.
