In astronomy, space refers collectively to the relatively empty parts of the universe. Any area outside the atmospheres of any celestial body can be considered 'space'. Although space is certainly spacious, it is not always empty, but can be filled with matter - say a tenuous plasma. In particular, the boundary between space and Earth's atmosphere is conventionally set at the Karman line.
Therby 'space' in astronomy, for us humans means the area outside earths atmosphere. In other words, the universe minus the earth and its atmosphere.
'Universe'on the other hand is..... everything.
The term universe has a variety of meanings based on the context in which it is described. In strictly physical terms the total universe is the summation of all matter that exists and the space in which all events occur. The part of the universe that can be seen or otherwise observed is usually called the known universe, observable universe, or visible universe. Because cosmic inflation removes vast parts of the total universe from our observable horizon, most cosmologists accept that it is impossible to observe the whole continuum and may use the expression our universe, referring only to that knowable by human beings in particular. In cosmological terms, the universe is thought to be a finite or infinite space-time continuum in which all matter and energy exist. It has been hypothesized by some scientists that the universe may be part of a system of many other universes, known as the multiverse.

Space is a content of the universe (in its grossest approximation)like the air in the balloon. Earlier it was believed that space and time were the two dimensions to describe the universe but after relativity theory it has become one by the name space-time

Yes. The universe is made up of space, matter and energy. There is a lot of space between our sun and its planets or between our solar system and the nearest star or between our milkyway and the next galaxie. There is also a lot of space between an atom's nucleus and its electrons and between atoms. Therefore there must even be space between the bricks in a wall. Matter is like the bricks in the wall and energy can move from brick to brick (to equalize temperature?). The universe is like the wall made up of all the bricks, energy and unoccupied space. The universe is "all" and space is an important ingredient that separates matter and requires time for energy (photons?) to traverse.

Space contains the universe.

space is anything. period.
universe is the entire possibility of anything out there. For example, if the possibility of outerspace is endless, which it is, as far as we know, then the universe is endless.
Space is everything within this known universe, everything from solid metal to black holes to air to no air...
