Can you explain to me how time is regarded as the 4th dimension? Does it mean that if we assume time as a dimension then an object traveling to different time period is possible?

Well, think of it like this, if I told you to meet me on the 2nd floor of 31st and Broadway, you would have 3 coordinates of where to meet me. Longitude, latitude, and elevation… But that’s meaningless without the 4th, what time? So 9am on Tuesday at 31st and Broadway on floor 2 is 4 dementions. Now time travel is a little above ELI5, because it involves much more complicated stuff, but assuming you could travel faster than the speed of causality/time (you can’t) time would effectively stop, or possibly go backwards, but that’s not possible, and you’d definitely not survive getting anywhere close to that speed (as my understanding)
