No. Available step current is inversely proportional to available step voltage.
For example, if you have a turns ratio of 10:1 for a typical step-down transformer running off of 120 VAC, producing 12 VAC; if the input current were 1 ampere, the output current would be 10 amperes. Similarly, for a step up transformer, available voltage goes up while available current goes down, all within the turns ratio.
Nope.
The current will be equal if the turns ratio is 1:1 in an ideal transformer. But, t/f s are not designed that way.
Further, Current ratio is equal to the inverse of turns ratio.

What will happen to frequency of current when voltage is changed using a step up or step down transformer?
Frequency does not change when you use a step-up or step-down transformer. Only current and voltage is changed.
Is ct step up or step down?
'CT' is used to designate current transformers, and 'PT' is used to designate potential transformers. A current transformer provides a ratio of primary current to the secondary. A potential transformer provides a ratio of primary voltage to the secondary. A power transformer (step up or step down) resembles a PT more than a CT.
What winding of a step-down transformer will carry more current?
Secondary.
Can you step up or step down the DC voltage by a transformer?
You need alternating current for a transformer, for DC you would have to interrupt the power supply to make it effectively DC pulses.
Why primary current is higher than secondary current in transformer with turns ratio 1?
In a transformer with a turns ratio equal to 1, the primary current comprises the reflected secondary current plus the magnetizing current necessary to sustain the "back EMF developed across the mutual inductance coupling the primary winding to the secondary. Therefore the primary current is always greater than the secondary current in a transformer with a turns ratio equal to 1. This should be evident by applying Kirchhoff's Current Law to the central node of the "T-equivalent" model of a transformer.
